Case study - Meat processors create new product with treatment

The Aire-O2® Microfloat’s immediate impact was a $100/day chemical savings

Problem

A southern USA red meat processor’s wastewater treatment was getting more complex and expensive but still did not yield the expected results. Regulations were getting stricter and stricter as well. The processor was spending $192 USD per day on ferric chloride to promote coagulation and settling but was still not satisfied with the results. The company decided to look at the Aire-O2®Microfloat Dispersed Air Flotation Systemthat is specifically designed for physical/chemical pretreatment of wastewater. The Microfloat’s removal of FOG before biological wastewater treatment greatly reduces the load for conventional facilities.

Solution

The meat processor installed two 7.5 hp (5.5 kW) Aire-O2Microfloat Dispersed Air Flotation units as a retrofit into existing tankage. The specially designed propeller disc on the Aire-O2® aerator’s shaft produces extremely fine bubbles, transferring 10 to 50 micron air bubbles into the water through special ejectors. The extremely fine bubbles attach to solid particles in the liquid and float these solids to the surface of the tank for easy removal by solids handling equipment. The immediate impact was conservatively saving more than US $100 per day on ferric chloride costs and increased production of more desirable float as rendering product. Removal rates exceeded 80 percent.

Results

The red meat processor had been paying to dispose of the float. But, with the production of more desirable float, the processor sold it as product. Additional benefits were reduced odors. Moisture levels in recovered materials were reduced which, in turn, reduces cook time for the float. Completely satisfied with the Aire-O2Microfloat’s performance, the meat processor installed two more additional units shortly thereafter. All of the equipment has been running almost maintenance free for years, even in this harsh environment.

Garden Grove, CA, May 5th, 2011
In 1986, California voters approved an initiative to address increasing concerns about exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.
Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or workplaces, or that are released into the environment. This list includes acetaldehyde,...

StockPot, a Campbell`s Soup subsidiary, makes premium soups, sauces, chilies and marinades for the foodservice industry.
To control odors from the cooking of meats, onions and other ingredients, StockPot purchased a Tri-Mer 40,000 cfm packed bed scrubber. Tri-Mer packed towers are well-suited to the foods and flavors industries and perform at efficiencies of 99% and higher. They are ideal for odors that are detectable below 1 ppm. And, where needed, they can simultaneously handle particulate as well.

AbstractThe rendering process consists of crushing and heating animal remains to produce by-products. The U.S. produces approximately 30 billion pounds of inedible animal by-products annually, exporting a market value of US$ 1.5 billion. Benefits of the rendering process include reducing total waste material, and helping the livestock industry stay competitive over vegetable protein manufacturers. However, the rendering process can have a negative effect on the environment through the emission of nuisance odorous...
